My little moded psu
EXTERNAL CASE: Deer psu company and it's metallic shiny new
FAN: ADDA from a Sparkle 250w psu
SLEEVED WIRES: OCZ STEALTH XSTREAM 600w
INTERNAL POWER: L&C computer co. Model: LC-B450E
1- Cleaned everything
2- Tested the fans to choose the one i'll put in.
3- Cutted all wires then figure out which wires would be useful or not.
4- Put back the 20+4 main plug, 4 pins cpu plug and a serie of 3 molex plugs.
5- Cut excedent wires at the source to be sure they don't ground somewhere.
6- Reassemble everything and test.
Just to show that you can get a good psu for free and with some spare time and a local computer store that give you their scrap for free.
Now I have a 450W psu that can throw 230w combined load on the +5v and +3.3v or 422w combined load on +5v, +3.3v and +12v with a 18A on the single 12v rail.
I also did the double power on the cpu plug to handle the overclocking. The cpu plug has 2 yellow and 2 black wires but i jointed the 2 yellow to 4 yellows wires on the board and same thing 2 on 4 for the black grounds.
